Some knowledge of edge banding hot melt adhesive film

Hot melt adhesive film refers to a thermoplastic adhesive material with polymer as the main body that is coated in a molten state and cured after cooling, and is 100% solid at room temperature.

Jiangmen M.F.B.S. Machinery Co., Ltd. is a company specializing in R&D, production and sales: medical protective clothing, outdoor sports clothing, footwear, leisure clothing, yoga coffee clothing, bags and other industries of special heat sealing tape, hot melt adhesive film, decorative film, seamless lamination materials. The relevant terms that characterize the characteristics of edge sealing hot melt adhesives are:

1. Viscosity: an indicator of fluid fluidity, high viscosity is poor fluidity. It is related to the properties of the fluid itself, temperature, concentration, shear speed, etc.

2. Thermoplasticity: under the action of heating or cooling, it can be repeatedly melted and solidified. The opposite is thermoset.

3. Opening time: refers to the large time interval between the glue from the glue to the surface can still be bonded to the substrate, and the glue has a good bonding effect during the opening time. It is related to factors such as glue, temperature, substrate, and glue amount.

4. Softening point: The material becomes soft when heated, close to the temperature of the flow.

5. Cohesive force: a microscopic statement of the strength of the material itself, similar to tensile strength.

6. Curing time: The glue is pressed between the two substrates until a strong bond is formed.

7. Thermal stability: the ability of the material to withstand high temperature for a long time.

8. Heat resistance: Under the premise that the bonding is not destroyed, the bonding system can withstand high temperatures.

9. Low temperature resistance: the ability of the hot melt adhesive film to maintain good adhesion strength or adhesion force at low temperatures.

10. Anti-aging: refers to the degree to which the bonding strength or adhesion of the bonding system changes with time during the storage process at room temperature.

11. Polishing: for the upper and lower polishing, can make the upper and lower sections of the edge banding tape regular and smooth.

12. Edge banding: The process of pasting the edge banding tape to the plate.

13. Cut-off: cutting off before edge sealing and cutting off after edge sealing is the process of cleaning the front and back remnants of edge banding tape.

14. Repair: generally divided into rough repair and refinement, is the process of cleaning up the upper and lower rubber and the remaining edge after the edge.

15. Wire drawing: refers to the filament that appears at the tail of the hot melt adhesive when the hot melt adhesive film is transferred from the coating head to the substrate, which is related to the nature of the hot melt adhesive film, the temperature of the glue and the coating method.
